Ddd - Dual Chamber Implantable Multiprogrammable Pacemaker With Shortest Programmable Av Delay
Of 50 Ms, With Matching Set Of Steroid Eluting Atrial And Ventricular Leads And Two Matching Subclavian Introducers.
Achieving an optimized AV delay
adjusts the contraction sequence between the left atrium and the left ventricle to optimize left ventricular filling without truncating atrial contribution.
and V-V interval are changed dynamically through an automated closed-loop optimization process.
Jurgen Vogt, Herz- und Diabeteszentrum Nordrhein-Westfalen, Bad Oeynhausen, Germany, commented, "The new Expert Ease feature saves us a lot of time, it gives us the additional ability to optimize the AV delay
and tailor the therapy to each patient individually by just pressing one button.
Despite 40 years of experience, the mechanisms whereby DDD pacing with short AV delay
reduces SAM and subsequent LVOT obstruction are not yet understood.
Other competitive features include SMART Success IEGM storage, Mode Conversion with programmable ventricular rate support, Dynamic AV Delay
to mimic normal physiologic shortening with exercise, Real-time IEGMs to facilitate troubleshooting and programming, along with a sophisticated EP Test Mode to evaluate defibrillation therapy thresholds and the efficacy of anti-arrhythmic drug therapy.
